Tagging versions? about golang-docker HOT 7 CLOSED

GCR has not been updated yet. I can update this thread when it gets updated.

from golang-docker.

Which image are you referring to? (I'm trying to learn how GCR mirrors docker hub)

from golang-docker.

I was referring to the GCR image gcr.io/google-appengine/golang which is accessible via the gcloud tool.

The latest version is now 1.8.

from golang-docker.

Ah got it. I am new to all this. I guess my 2 questions:

1. Do we always have :latest instead of :1.6, :1.7, :1.8?
2. How do you access that image via gcloud?

from golang-docker.

1. Yes. I think w/o specifying a tag, it will fetch the latest.
2. To fetch the Docker image ...
   $ gcloud docker -- pull gcr.io/google_appengine/golang:latest

from golang-docker.

Yes. I think w/o specifying a tag, it will fetch the latest.

I understand, but my question was more like, do we have tags at all or is it only :latest? I am asking this because don't see any tags like :1.6 or :1.8 documented/listed anywhere (in README at least) so I am assuming :latest is the only tag that exists?

$ gcloud docker -- pull gcr.io/google_appengine/golang:latest

Ah got it, then docker pull gcr.io/google_appengine/golang:latest works just fine without gcloud too. I got confused for a moment when you said "accessible via gcloud". I think it's just a public image accessible from anything that can pull Docker images.

Yeah, we didn't document that. You can see all the tags by running ...

gcloud beta container images list-tags gcr.io/google_appengine/golang

We'll make sure to have the major version tag so users can use that to pin a particular version.

Good to know. I didn't know that docker can pull directly from GCR. I'm new at this too:)
